Riverside County tap water is safe to drink by EPA standards, but “safe” doesn’t always mean “pure” or “great-tasting.” Municipal water from the Metropolitan Water District contains chlorine, chloramines, fluoride, and naturally occurring minerals that affect taste, smell, and quality. Davis Plumbing and Heating Inc. installs reverse osmosis (RO) water filtration systems throughout Murrieta, Temecula, Menifee, Perris, Lake Elsinore, and the entire Riverside County area.

What Is Reverse Osmosis Filtration?

Reverse osmosis is a multi-stage water purification process that forces tap water through a semi-permeable membrane under pressure. The membrane rejects up to 99% of dissolved solids, contaminants, and minerals — including chlorine, chloramines, lead, arsenic, nitrates, pesticides, and many other impurities. The result is water that’s as close to pure H2O as you can get from a tap.

What RO Removes from Riverside County Water

  • Chlorine and chloramines — Used by water utilities to disinfect water but responsible for that “pool” smell and taste.
  • Lead and heavy metals — Can leach into water from older plumbing fixtures and supply lines.
  • Hardness minerals — Calcium and magnesium that make water “hard” and leave scale on appliances and fixtures.
  • Total Dissolved Solids (TDS) — A measure of all dissolved minerals. Riverside County tap water TDS is often 400-700 ppm. RO water typically measures 10-30 ppm.
  • Nitrates — Agricultural runoff contaminants that can affect groundwater in parts of the region.
  • Fluoride — Partially removed by RO (50-90% reduction).

How an Under-Sink RO System Works

A residential under-sink RO system fits in the cabinet below your kitchen sink. It consists of pre-filters (sediment and carbon), the RO membrane, a post-filter, and a small storage tank. Most systems produce 50-75 gallons per day — more than enough for drinking and cooking. A dedicated dispensing faucet is installed at the sink for clean, purified water on demand.

Cost of RO Installation in Riverside County

  • Entry-level systems (3-stage) — $200-400 installed
  • Premium systems (5-6 stage with remineralization) — $400-800 installed
  • Filter replacement — $50-150 per year depending on usage

Compare this to $1,200+ per year on bottled water for a family of four. RO typically pays for itself in 6-18 months.

Whole-Home Filtration vs. Under-Sink RO

An under-sink RO system provides the purest drinking and cooking water at one tap. A whole-home carbon filter improves water quality for bathing, laundry, and all fixtures but doesn’t achieve the same purity level as RO. Many Riverside County families choose BOTH — a whole-home softener/filter combination plus an under-sink RO for drinking water.
